PADLOCK.

SPECIFICATION forming part of Letters Patent No. 380,961, dated April10, 1888. Application filed September 26, 1881'. Serial No. 250,719. (Nomodel.)

To all whom it may concern:

Be it known that we, DAVID \VAINE and ISAAC WAINE, subjects of HerMajesty the Queen of Great Britain, both residing at W'illenhall,in thecounty ofStafford,England, have invented certain new and usefulImprovements in Padlocks, of which the following is a speoification.

This improvement in padlocks consists in a I novel arrangement,construction, and combination of certain of the parts as hereindescribed, whereby padlocks are rendered selflocking and more secure,and advantages are obtained in the manufacture, as hereinafter setforth.

We will describe our invention by referring to the accompanyingdrawings, in which- Figure 1 is front elevation, and Fig. 2 a sideelevation, of a padlock constructed according to our invention, thepadlock being represented, as locked. Fig. 3 is a front elevation of thesame unlocked. Fig. 4 is a front sectional elevation, and Fig. 5 is aside sectional elevation, of the same locked. Figs. 6 and 7 are frontsectional elevations of the same, the lock being represented as unlockedin Fig. 6 and almost locked in Fig. 7. Fig. 8 is a plan of the casing ofthe same. Figs. 9 and 10representdetailsofthesanie. Fig. llshows thesame lock with an enlarged shackle. Figs. 12 and 13 are part frontsectional elevations, and Fig. 14 is a part side sectional elevation,and Fig. 15 a partial plan, of a modified form of padlock represented bythe preceding figures; and Figs. 16 and 17 represent details of the saidmodification.

Referring first more particularly to Figs. 1 to 10, both inclusive, inall of which the same letters of reference indicate the same parts, A isthe padlock-case, a is the key-hole, and B is the bolt of the lockprojecting through a rectangular hole, a, in the top of the casing. Theprojecting part b of the bolt B is bowshaped, so as to form part(preferably one half) of a ring'shaped shackle, the other half, D, ofwhich is made loose from the bolt B, and is hinged or jointed thereto bya pin, 6, formed on the bolt B passing into a hole, (1, in a side ear ofthe piece D. The end of the pin 0 is riveted over, so as to form a loosejoint. The pin 6 is, for the purposes hereinafter described,

D form in cross-section a rectangle when together and fit in the opening0 in the top of the casing. (See Fig. 8.) A shoulder, g, is provided atthe neck of the bolt B and the loose bow D, which fits against the topof the casing when the bolt is withdrawn, as hereinafter described. Thelower end, d, of the loose bow D is squared off, so as to bear against astop, a in the case when the bolt is in its locked position.

The internal mechanism of the padlock -th'at is, that part of the bolt Bwhich is inside the case and is operated on by the key z to shoot thebolt forward or to withdraw it, and the mechanism for maintaining thebolt in either its forward or withdrawn positions-may be similar to themechanism employed in other looks. The internal mechanism represented bythe drawings is similar to that used in some lever-locks, j being thetumbler turning on a fulcrum, k, and having at its free end a notch, Z,which engages with a projection, m, on the bolt B when the bolt is inits locked position. The tumbler is moved sidewise to free the bolt, andthe bolt moved forward or withdrawn in the wellknown manner by turningthe key i.

The operation of the padlock above described is as follows: WVhen thebolt Bis shot back into the case, (see Figs. 1, 2, 4, and 5,) thepadlock is looked, as the pin 6 on which the loose bow D turns is theninside the case A, which latter, as the necks I) d fit in the hole 0,holds the loose bow D locked against the bow part bof the bolt B, andthe end d of the bow D takes against the stop a inside the casing. WVhenthe bolt B is shot forward, (see Figs. 3 and 6,) the padlock isunlocked, as the pin 6 will then be outside the case, and the loose bowD can turn on its joint and be opened out from the bow b of the bolt B,so as to allow of the padlock being locked onto or removed from a stapleor the like, as may be required.

This padlock is selflocking, as on pushing the boltB inward theprojection in on the bolt through the bolt.

acts upon the inclined endj of the tumblerj, and pressing the saidtumbler sidewise (see Fig. 7) passes into the notch land locks the bolt.

In order to more effectually prevent the shackle being wrenched open bytwisting the outer ends of the two parts b D sidewise, we form aprojecting pip, n, on the end of one part, which, when the padlock islocked, fits into a corresponding hole, 0, in the end of the other part.

Instead of one only of the halves of the shackle being made loose fromthe bolt B, as above described, both halves may be made loose andsimilarly hinged to the bolt B, as in the modification illustrated byFigs. 12, 13, 14, 15, 16, and 17. The two halves of the shackle arerespectively marked Dand D At the bottom of each of the parts D D is apair of ears,

those on D being marked 9 p and those on D being marked g g. The end I)of the bolt B fits between these ears, and they are there jointed by apin, 1, passing through them and As in this case the hole a does notform a guide for the bolt, an additional guide, 8, is formed inside thecase, between which and the stop a the boltB can slide. The parts whichwe have not described in this modification are similar to correspondingparts in the padlock hereinbefore described, and illustrated by Figs. 1to 10, both inclusive.

In the manufacture of these improved padlocks there is aconsiderableadvantage, as the size of the shackle can be varied withoutaltering the size of the padlock-case and the mechanism containedthereinforinstance, as shown by Fig. 11, where the size of the shackleis considerably increased without altering the casing A.

It will be evident that the shape of the shackle can be varied withoutdeparting from the nature of our invention, as instead of beingring-shaped it may, for instance, be a hollow triangle or an oval ring,and it may be so divided that one arm or how is larger than the other.

What we claim as our invention, and desire to secure by Letters Patent,is-

1. In a padlock and in combination, a nonrotating case, a shackle formedin two parts, a sliding support for said parts, and operating means forthe sliding support, substantially as described.

2. In combination, the case, the shackle formed in two parts, a slidingsupport, B, the pivot-point e of the two parts of the shackle being onsaid support and adjacent to the opening in the case, a tumbler andoperating means for the support, whereby the pivot may be thrown intoand out of the case, substantially as described.

In testimony whereof we have each signed in the presence of twosubscribing witnesses.
